Hey I’m Justin with AmericanMuscle.com, and I have with me possibly one of the best live axle handling modification you can do, thanks to Whiteline’s Watts link rear suspension setup, fitting all 2005 and newer Mustangs. The Mustang’s solid rear axle has unfairly been the subject of much criticism over the years, and is oftentimes considered to be the weak point of handling performance. The truth is, the modern live axle can be just as good as an independent rear setup, given a little help, that help comes in the form of this Watts link from Whiteline. The Watts link is designed to replace the factory Panhard setup in your Mustang and prevent any lateral or side to side movement of a rear axle. Even though the Watts link and the Panhard bar are essentially one of the same, the Watts link is a far superior design. The Panhard bar mounts to one end of the chassis, and connects to the far side of the axle, and while yes, this does do a great job of preventing any lateral movement, the Panhard bar does have one flaw, vertical movement. When the suspension moves up and down, the Panhard bar has the tendency to move in an arc, rather than up and down, this can result in an varying roll center which basically translates into less handling predictability, coming into or out of a turn. The design of Whiteline’s Watts link allows the rear axle to move up and down, thanks to these 2 arms that mount to each side of the chassis, and pivot right here at the diff cover. This allows the roll center to remain constant no matter what the car is doing, turning, centering, it all translates to increased handling predictability, and a more stable, planted rear end. Taking a closer look you can see this total package from Whiteline is no joke, almost the entire thing has been constructed using quality 4130 chromoly steel, and features Whiteline’s unique elastomer bushings. Perhaps one of the biggest features of this kit besides the full adjustability, is the fact that it includes a brand new diff cover, making this product a 100% bolt on affair. Because this kit does bolt on, the install really isn’t all that bad, and can be accomplished in the garage on a Saturday or Sunday afternoon. Keep in mind, since the factory diff cover will be coming off, make sure you have a drain can on you to capture all that fluid when you do crack the pumpkin. With that said, make sure you have a couple of quarts of fluid to fill the diff back up when everything is installed. When it’s all said and done, you should be wrapped up in about 4 or 5 hours. So if you’re the type of Mustang owner who prefers the twisty back roads or autocross track to the drag strip, and you want to take your live axle car to the next level, then be sure to check out this complete Watts link system from Whiteline, available right here at AmericanMuscle.com

Awesome product, makes the body and chassis feel more like one . It took out the body sway in the twisties and When accelerating hard rowing through the gears. Before the watts system It felt more loose on one side than the other and it removed that feeling. It’s now solid when banking left to right. Only complaint is I had no instruction with the kit. it also took a lot more than just 2 qts of diff fluid to fill if your going to fill it untill it comes out the top plug hole on the diff cover so grab extra. I would say time to install a full day because I broke most the tools needed trying to get the car apart and also broke a bolt when torquing some of them down. It is an easy install tho It just took time. Well worth it and it looks sexyHelpful (1)

Quality watts link with a few minor issues
Was very excited to install a watts link on my car so it would handle better and keep the rear axle centered. I went with the whiteline unit because it looks the best out of all the watts links for the s197 in my opinion, and it has a good reputation with companies like vorshlag using it with good results. Install wasn't too bad, although the instructions tell you to do things a bit backwards. Best way to do it is to get the diff cover installed and fill it with fluid before connecting the rest of the components. I did run into one issue while installing the center pivot support. The bolt just to the left of the center pivot (M12 x 20mm) is supposed to be torqued to 40 ft*lbs per the instructions. I followed these instructions and ended up stripping the bolt hole. Searched the forums and this seems to be a common issue with this watts link. Luckily I was able to get a slightly longer bolt from the local hardware store and there were still some threads left in the hole that I was able to tighten it sufficiently. So if I had to do it all over again I would not torque that bolt and just put some loctite on it and get it tight with a 3/8" drive socket. Another pain was getting the arms adjusted after everything was installed. The driver's side bar is easy to adjust, the passenger side, not so much. Tightening the jamb nuts was a pain, but I finally got it. Its easier to tighten them if you remove the support brace, which i did. I haven't had a chance to test the watts link much but I think I can tell a bit of a difference when going over bumps. This is definitely not a cheap mod, but its worth it to get rid of the negative aspects of having a solid rear axle car.Helpful (6)

Wheel hop nonexistent
Mustang came with Watts Link, put about 60 thousand miles on it, hard launches, rolling burnouts, San Diego back roads (Sunrise Highway). Car stays planted, good set up with the orange Koni Shocks and Struts. Look on YouTube at Dude in Blue Watts Linkage. Must on live axle MustangsHelpful (10)

Not as easy you might think
Not totally satisfied with the quality. Took me far longer then it should of. Screwing the bolts in to the rear end cover felt like I was cutting new threads the whole way in. One actually stripped out the threads, the bolt never got tight enough to stop the washer from spinning freely. Had to tap the hole with 1/2 tap and a1/2 inch bolt cut down enough to not bottom out. Then the brace was too long or the holes not drilled in the right place. Had to drill and file the holes to get the passenger side holes to line up. Other then that every thing else went smoothly. Looks good and did improve the handling. Would buy again but I now know what I am getting.Helpful (10)

Install was straight forward. I was very pleased with the ride and handling. The best way I can describe it was that the car felt smoother thru the corners. I haven't experienced any additional noise but I probably only have 500 miles on the car since the install. Great looking but you will never see it.Helpful (6)

Does not work with steeda sway
This was the best suspension mod to date; however i had to modify the passenger side link for my steeda sway bar to make it all work. Either plan ahead for this and get one that works or be prepared to do some grinding. Therefore, install time took me longer.Helpful (6)

The setup isgreat and took me a little to long for a first time install, the Instructions are straight forward. Since it was my first try kept forgetting, not to jump ahead of steps. The stock fill plug is useless since new cover has a filler plug in back. Took longer to fill oil. But after a long day the car feels different. Great. Now I know it is great investment, now I can lower my mustang.Helpful (8)

Best modification available!!
So first of all, the install was not too terrible what so ever. I was alone and it took my four hours with a jack 2 stands and all hand tools. Make sure you get diff fluid before you begin the install though! That aside, I don't know why Ford let their mustangs leave without this product on the car. It's absolutely transformed the feel. It's more comfortable on the freeway and around town, way more predictable in corners, and turns absolutely amazing. 5 star no brainer.Helpful (12)

Feels like a different car
Give yourself a full day to install this and take your time. Read the instructions prior and obtain all of the required tools and products required to keep your stress level at zero. Save all of the factory hardware because you will need to reuse some of it. The instructions are a little vague in some areas but if you have any mechanical ability you will be able to get through it with no problems. The fit and finish it top notch. The ride feels much smoother, better held together and even dampened. I took it on some hill climb twisty's and felt very confident. It's still new to me but I'm loving it so far!Helpful (10)

The Whiteline Complete Watts Link Rear Suspension will work with the BMR Xtreme Rear Sway Bar Kit
Swarr Bar compatible? Can a swarr bar be installed along side the watts link setup? swarr bar Item # 80801 for reference Thanks
Yes the Swarr rear end support will fit with this Watts Link. The Swarr support sits below the differential and out of the way of the Watts Link.
2013 GT500 fitment. Can you explain how the oil lines from the track package work with this? Very interested but not getting how the watts link will work with this setup.
The Whiteline Complete Watts Link Rear Suspension would not be compatible with the Differential Cooler.
will it fit to Ford Performance Rear Sway Bar M-5490-A ?
Yes, The Whiteline Complete Watts Link Rear Suspension will indeed work with a Ford Performance Rear Sway Bar (M-5490-A).
Hello! The Whiteline Complete Watts Link Rear Suspension will allow the oil lines from the track pack to connect to the new differential cover, retaining the oil cooling system on the differential.
The Whiteline Complete Watts Link Rear Suspension (05-14 Coupe) cannot lower or raise the vehicle. When it says, "Adjustable Ride Height", it simply means that you can adjust the bushing to accommodate any ride height. The silver pieces on the differential cover can move multiple ways for different ride heights. This will work for stock and lowered vehicle.
The Whiteline Complete Watts Link Rear Suspension will not fit the 2006 Convertible Mustang.
This can be taken apart, yes. Dimension not available.
We would not carry any watts links for the convertible models. The closest thing you can do on the convertible models would be to just replace a lot of thesuspension components like the sway bars, control arms, springs, shocks, and struts.
The Whiteline Complete Watts Link Rear Suspension will require no cutting, welding, or drilling for installation.
This will work with the track pack mustang, the whiteline watts link system is an excellent system over the track pack setup.
Yes, this rear suspension kit would be able to used in unison with an air ride suspension.
You are able to use the Watts Link with the RTR rear swaybar. If you check out item #383782 webpage, you will see that the 2nd customer submitted photograph has the swaybar used in conjunction with the Watts Link rear suspension.
A convertible is built at the bottom because it does not have a solid roof. This Link Rear Suspension will not be able to fit on a convertible since there is no room for it.
